The Bad Boy is a pretty nice hybrid- with the price to match.
Main reason for even considering a mtb is the fact that an entry level model with discs are roughly $150 or more less than a hybrid with discs. And my logic might be flawed, but mtbs should have beefier wheels that equate into them not going out of true as much.
The rear wheel on my bike is making the same racket that it did before when I broke a spoke (checked this time and didn't find any) and will only get worse the more I ride it. Dunno, maybe the wrenches at my primary LBS aren't as good as I thought or maybe since I have had to have the rear trued twice already, maybe it's time for a new wheel.
However, the frame is a tad too big for me (but doable), and I suffer heel strike. If I thought even for a second that the shop I got it from would allow me to trade, I'd strongly consider it and walk until I could pay off the balance owed on any new bike.
But enough about the drama that is my life story- what about the whole purpose of the thread, you know "how to pick a mtb for commuting duty"?
